How much water got in the engine? If the oil is clean and just some residue in the cylinders then start and run the engine. Run it at idle for at least 30 minutes keeping watch of the temperature. As long as you now are getting good fuel through the engine you should be fine. Did you drain the fuel supply module? There is a fuel pump inside and a drain on the bottom. As long as that is full of good fuel any small amount in the lines will be forced out. the engine may be balky to start at first or run rough.

Jeff thanks for the reply I only emptied the clear fuel filter that's on the front of the motor that is closest to the boat and then emptied all the bad fuel from there on back where is the drain plug for this fuel supply module is it port or starboard

It is a silver tank behind the intake runners. Remove the cowls and the drain screw is on the very bottom.

I drained the reservoir unit of all the bad fuel pump completely good fuel through the entire system then started it and ran it for 30 to 40 minutes the motor runs great but the fuel water contamination symbol is still on the tachometer command link unit on the console. Does not have to be reset or is it still have watered fuel in the motor
